2 Things: 1) Please don't repost if your question does not appear immediately: all of these went to moderation and required a human being to review them for publication. In order to prevent you being kicked off as a spammer, both had to be accepted, and then I have to clean up the spares. Have a little patience, please! I've deleted the 3 identical spares ... 2) Don't post this under Quick Answers - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them. Posting this here relies on them "dropping by" and realising it is for them. However, given that the article is 22 years old it's unlikely that anyone is going to know or remember details of how it works!
